When VIDA Middle School in Vista, California, received a grant to hand every one of its 680 students an iPad with a free 4G connection, parents were excited.

They were also a little nervous.

"We have a large population of students who walk," says Principal Eric Chagala. "The fear was, you are putting a $700 or $800 device in my 11-year-old's hand, and they have to get home."

So, Chagala hit the streets of the working class neighborhood around the school. He talked to local police. He dropped in on area pawn shops, to ask them to call the school if people started showing up with iPads to sell.
